Product details

Its description — XT4H 250 TMF 250-2500 3P F F UL/CSA — tells you it's a 250 A frame with fixed thermal and fixed magnetic settings, front-connected terminals, and UL/CSA certification for North American panel builds.

What the TMF 250-2500 trip unit means for your panel

The TMF 250-2500 trip unit is a thermal-magnetic design: the thermal element protects against sustained overloads (heating curve), and the magnetic element handles short-circuit instantaneous trips. For a panel builder wiring a 250 A feeder, this is the code-compliant choice — no need to spec a separate UL-listed disconnect ahead of it if the breaker itself is the branch-circuit protective device.

Frequently asked questions

What is the closest pin-compatible alternative to the XT4HU3250AFL000XXX in this family?

Within the ABB XT4H series, the closest alternative would be a variant with a different trip unit rating or terminal configuration, but the evidence does not list a specific pin-compatible substitute. For a direct replacement, the TMF 250-2500 fixed trip and UL/CSA certification are the defining specs — any alternative would need to match those exactly.
